i have a infrared receiver with 3 pins coming out of it,if im looking at the receiver lense where do the pins go ,(the left pin,middle,and right)
any help would be great.....

 

you have to know the part number, then look at the spec sheet.

That is the only way unless you want to guess, but then you can render your part useless, as well as other parts in the same circuit.

 

do you know what the pins do , is one +v and 0v and base

 

one of the pins is ground, one is +V (probably 5V) and the other is the signal. ground should be quite obvious, maybe even connected to the metal case. If you can see the circuit board, +V should be fairly easy to discern.

best way, though, is as johnsmith said - get the part number and find the datasheet.

 

i got the data sheet its at www.jaycar.com.au and the part number is zd-1952 but the picture is to small for me to see

 

It is a FDF datasheet and when you zoom in on it then it is easy to see.

thanks i set it up , i used a 5v regulator on pin 3 and i grounded pin 2 but pin 1 is showing about 1.19 volts without transmitter and about 1.28 with the transmitter shouldnt it be oV without transmitter

 

Its output should go low if it receives an IR beam that is modulated with its carrier frequency, and go high in the dark. Its output doesn't change as much as it should so it must have daylight or a compact fluorescent bulb shining on it.

i connected pin 1 (output) to pin 3 (+V) with a LED,and i got the tv remote and pressed a button and the LED started flashing,is that the way it is supposed to work???

 

Yes it is, the flashing is the demodulated data from the remote.

i tried making a transmitter with a standard collector emitter transmitter LED but im getting zero results with it, the tv remote is working excellent with over 20 meter rang and it flashes due to the tv remote,is there a simple way to set it up so it stays on rather than flashing.

 

You need to modulate the LED with 38KHz or so - bear in mind though that the receiver is designed for data pulses, and NOT for continuous carrier - so range will probably be considerably reduced.

does anyone know how to modulate a standard infrared led for the receiver

 

You turn it on and off at about 38kHz with an oscillator. A 555 oscillator is powerful enough for it.

how do i get the 38kHz , what do i have to do?
